Flight Management System (FMS) for the Agusta AW139/AB139 Helicopter
FUNCTIONAL DESCRIPTION
The FMS combines the inputs of other aircraft systems to output
navigation, lateral and vertical commands, and aircraft performance
predictions and shows data through the MCDU and the EDS. Displayed
data includes:
A map presentation showing:
D
— Radio navigation aids
— Airports and Heliports
— Waypoints on the active flight plan.
Airspeed targets.
D
FMS mode annunciators.
D
The navigation function computes the aircraft position and velocity for
all phases of flight (oceanic, en route, terminal, and approach),
including polar navigation.
The navigation function automatically blends or selects position
sensors to compute an optimum position.
The pilot deselects individual sensors, when required.
Flight Planning
The flight planning function computes the active flight plan with both
lateral and vertical definition. Flight plans are loaded from a laptop
personal computer (PC) using the data multiplexing unit (DMU)
interface.
Database
The database contains worldwide coverage of navigational
(navaids), airways, standard instrument departure/standard terminal
arrival route (SID/STAR) procedures, approach procedures, airports,
runways, heliports, and helipads. The database also stores
pilot--defined flight plans and waypoints.
Lateral Navigation (LNAV)
LNAV guides the aircraft along a predetermined flight path at a
pilot--selected bank angle for increased passenger comfort. LNAV
maintains the aircraft within an airway or protected airspace. LNAV
automatically flies pilot--defined or database holding patterns, including
entry and exit procedures.
